Ken Jucks is the Program Manager for the Upper Atmosphere Research Program (UARP). He came to NASA HQ as an IPA detailee from the Smithsonian Astrophysical Observatory (SAO, part of the Harvard-Smithsonian Center for Astrophysics) in Cambridge, MA. He has been an HQ NASA Civil servant since 2009. UARP concentrates on the processes that control ozone concentrations in the upper troposphere and stratosphere, and therefore surface ultraviolet radiation. The program funds numerous laboratory and field campaigns that contribute to quantifying our scientific understanding of ozone changes. Typical laboratory studies include kinetics studies of key reactions that either directly or indirectly destroy and create ozone or the precursors to ozone destroying compounds, as well as spectroscopic studies required to accurately monitor the key atmospheric constituents. Typical field studies include airborne in situ and remote sensing instrumentation for focused aircraft field campaigns, high altitude balloon remote sensing and in situ observations, and long term ground based in situ and remote sensing programs.
